Filters
-
In order to minimize filter roll-off, we start with a quality, highly polished substrate and apply layers of metallization within tight tolerances. Our highly anisotropic ion beam etching process enables us to produce features down to 10 microns. Furthermore, the milling process yields a high consistency from circuit to circuit meaning that whether we produce 1 or 100,000 filters, each one will have consistent filter roll-off characteristics.

DC Filter Inductors
-
Osborne DC filter inductors (aka filter chokes) are commonly used in AC to DC conversion circuits to present an inductive voltage drop to the AC component of rectified current. This inductive voltage drop acts as a filter. Osborne designs filter inductors to components to function effectively (without saturation) in the presence of the DC current. Osborne will work with you to mitigate the impact of ripple frequency in conversion circuits. Every Osborne DC filter choke is designed for high performance with special consideration given to your circuit´s power supply frequency and conversion configuration.

Gas Filter Correlation CO Analyzer
Model T300U
-
Teledyne Advanced Pollution Instrumentation
The Model T300U Trace-level CO analyzer has been developed specifically to address the challenges of low level monitoring as required, for example, in the US NCore network. Using IR absorption with a Gas Filter Correlation Wheel, the T300U is designed to allow ultra-sensitive CO measurements while still meeting the requirements for use as a US EPA compliance analyzer.The optical bench is enclosed in a temperature controlled oven, dramatically decreasing instrument noise and drift. The objective and field mirrors in the sample cell are gold plated to maximize signal to noise performance, while a temperature-controlled Nafion dryer on the inlet minimizes water interference caused by ambient humidity changes. Periodically, the T300U seamlessly corrects its baseline by routing the sample through a heated catalytic CO scrubber. This Auto Reference function corrects zero drift and reduces the effect of interferences.

Gas Filter Correlation Carbon Dioxide Analyzer
Model T360
-
The Model T360 CO2 analyzer measures Carbon Dioxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high-energy IR light source is alternately passed through a CO2 filled chamber and a chamber with no CO2 present. The light path then travels through the sample cell, which has a folded path of 2.56 meters.The energy loss through the sample cell is compared with the reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing excellent performance over a wide concentration range.All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports, either locally or by remote connection.The Model T360 comes with NumaView™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.
